' To all whom t may concern:

Beit known that I, ANTON LATER, a citizen of the United States, residing in the city and county of San of California, have invented new and useful Improvements in- Separators, of which the following is a speciication.-

This invention relates to a seed separator.

Experience in the separation of seeds, beans, etc., from chaff, adobe lumps, stones and other similar foreign matter hasshown that there has been a need for a separator which would do away with skilled operators; eliminate a complex method of separation; reduce the cost of power to operate; and make a more perfect separation without the loss of a large part of the good product which goes in with the foreign matter.

One of the objects of the present invention is to provide a simple, compact, easily operated separating machine of the character described by which gravel, adobe lumps, stones and chaff may be separated from beans, peas, or seeds in general. Further objects will hereinafter appear.

The invention consists of the parts and the construction and combination of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings in which- Figure 1 is a side elevation of the separator. Fig. 2 is an end view of same. Fig. 3 isy another end view showing the driving mechanism removed.

The separator consists of a pair of parallelly disposed rollers 2 and 3, of suitable length, which are secured upon shafts 4 and 5 journaled in bearings 6 and 7 which are mounted upon a rectangular-shaped frame 8. This frame is pivotally mounted at one end, as indicated at 9, upon a driving shaft 10, which in turn is journaled in a main stationary frame A; the other end of the frame being supported by a pair of adjustable links 11 which may be raised or lowered to regulate the inclined position of frame 8 and the rollers the-rein by means of the mechanism generally indicated at 12.

The separating rollers 2 and 3 are in this instance independently driven by means of the bevel gears, indicated at 13, the rollers being driven in opposite directions or away from each other, as indicatedby the arrows 0;. The bearings 6 and 7, in which the rollers are journaled, are slidabl mounted in a bearing plate 14. by a suita le means, or, as

Francisco and State here indicated, by the right and left-hand threaded screw 15 which projects through threaded lugs 16 formed on the ends of the respective bearings. The adjustable mountlng of the bearings 6 and 7 permits the rollers to be brought into close contact with each other or slightly separated as will hereinafter be described.

Mounted centrally between-the separating rollers, at a suitable distance above same, is a square-shaped deector 17. This deilector is carried by a pair of cross bars 18 which are secured in adjustably mounted uprights 19 secured on the side of the main frame 8.

In operation, in Separating beans, peas, or like leguminous products, it is only necessary to provide a hopper, such as indicated at 20. The beans are fed from the hopper and delivered between the up er elevated ends of the rollers. The sur ace of the rollers is preferably smooth and polished and will in this manner permit the beans to' gradually slide down and discharge at the lower end of the rollers. A slight separation or space formed between the rollers permits small stems, gravel, adobe lumps, and the like to drop between the rollers, thus getting rid of a certain portion of the objectionable material Within which the beans are generally contaminated. The larger particles of objectionable material are generally rough and will adhere to the face of the rollers and will thus be carried over by same as these revolve away from each other. Tn handling different grades of material it is very essential to adjust the speed or revolution of the rollers. rlhis is accomplished in the present instance by providing a pair of cone-shaped driving pulleys, such as indicated at 21. The speed of the rollers can then be adjustedto a nicety, thus increasing the utility and eliiciency of the separator as a whole. rThe .undesirable products carried over by the rollers sometimes have a tendency to jump and fall back. This is, in the present instance, practically eliminated as they strike one of the surfaces of the squareshaped deflector. If a particle, like a lump of adobe, strikes the lower surface of the deiiector it will naturally be thrown out in the direction of the arrows b. lf the particle jumps sufficiently high to strike the upper surface of the deflector it will also be deilected outwardly, as indicated by arrows c.

The inclined position of the rollers and justment provided by means of the pivotal mounting of the frame, permits a large capacity and high eiiiciency. The separator,

furthermore, improves the luster and finish of the product handled, as the smooth surface of the separating rollers has a tendency to polish the product as it passes downwardly between the rollers, thus increasing the marketable value of the product.

The materials and finish of the several parts of the apparatus are such as the eX- perience and judgment of the manufacturer may dictate.

I wish it understood that various changes in form, proportions, and minor details of construction may be resorted to within the scope of the appended claim and that I do not wish to limit myself to the specific design and construction here shown.

The adjustable mounting of the square shaped deiiector box is of considerable importance as it permits the deilector to be raised or lowered with relation to the rollers into the most effective position when handling different grades of material. It also permits one end to be raised and the other lowered, or vice versa. This is of considerable importance when handling j beans, for instance. It has been found in actual practice that when the upper end of the deiiector is raised practically all the adobe lumps will be thrown oi near the upper end of the rollers and that shriveled or defective beans and other defective material will be thrown off near the lower discharge end of the rollers or where the spacing between the deiiector and rollers is smaller. It is thus found that various products can be thrown off at different points by simply vadjusting the position of the deilector. Onel or more adjustable partition plates, such as indicated at 32, may thus be laced below the rollers to separate the di erent grades of material thrown ofi" by the rollers. For instance the adjustable partition indicated at 32 would separate the adobe lumps from the shriveled beans.

Having thus described my invention what I claim and desire to secure by Letters Patent is- The combination with a main supporting frame, of a pair of parallelly disposed rollers journaled in the frame, driving means for each roller, a deiector plate centrally mounted between and above the rollers for vertical adjustment to obtain a variance in the separation of the material, and an adjustable partition member pivotally mounted below the rollers for adjustment to accommodate for adjustment of the deflector.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

ANTON LAUMEISTER.
